We attribute (allocate) the impact on the Fund&#x2019;s performance into three components. The first of the three components is the impact on the Fund&#x2019;s performance due to changes in the &lt;/i&gt; &lt;i&gt;Fund&#x2019;s&lt;/i&gt; &lt;i&gt; Reference Asset. The second component is the aggregate impact on the Fund&#x2019;s performance due to changes in other variables that impact FLEX Options prices - these include changes in a) the Reference Asset&#x2019;s dividends, b) interest rates, c) implied volatility, and d) time to option expiration. &lt;/i&gt; &lt;i&gt;The third component is from the Fund&#x2019;s fees and &lt;/i&gt; &lt;i&gt;expenses incurred during the Period.&lt;/i&gt; &lt;/div&gt;</oef:FactorsAffectingPerfTextBlock>

The second component is the aggregate impact on the Fund&#x2019;s performance due to changes in other variables that impact FLEX Options prices - these include changes in a) the Reference Asset&#x2019;s dividends, b) interest rates, c) implied volatility, and d) time to option expiration. &lt;/i&gt; &lt;i&gt;The third component is from the Fund&#x2019;s fees and &lt;/i&gt; &lt;i&gt;expenses incurred during the Period.&lt;/i&gt; &lt;/div&gt;</oef:FactorsAffectingPerfTextBlock>

The second component is the aggregate impact on the Fund&#x2019;s performance due to changes in other variables that impact FLEX Options prices - these include changes in a) the Reference Asset&#x2019;s dividends, b) interest rates, c) implied volatility, and d) time to option expiration. &lt;/i&gt; &lt;i&gt;The third component is from the Fund&#x2019;s fees and &lt;/i&gt; &lt;i&gt;expenses incurred during the Period.&lt;/i&gt; &lt;/div&gt;</oef:FactorsAffectingPerfTextBlock>

The first of the three components is the impact on the Fund&#x2019;s performance due to changes in the &lt;/i&gt; &lt;i&gt;Fund&#x2019;s&lt;/i&gt; &lt;i&gt; Reference Asset. The second component is the aggregate impact on the Fund&#x2019;s performance due to changes in other variables that impact FLEX Options prices - these include changes in a) the Reference Asset&#x2019;s dividends, b) interest rates, c) implied volatility, and d) time to option expiration. &lt;/i&gt; &lt;i&gt;The third component is from the Fund&#x2019;s fees and &lt;/i&gt; &lt;i&gt;expenses incurred during the Period.&lt;/i&gt;&lt;/div&gt;

We attribute (allocate) the impact on the Fund&#x2019;s performance into three components. The first of the three components is the impact on the Fund&#x2019;s performance due to changes in the &lt;/i&gt; &lt;i&gt;Fund&#x2019;s&lt;/i&gt; &lt;i&gt; Reference Asset. The second component is the aggregate impact on the Fund&#x2019;s performance due to changes in other variables that impact FLEX Options prices - these include changes in a) the Reference Asset&#x2019;s dividends, b) interest rates, c) implied volatility, and d) time to option expiration. &lt;/i&gt; &lt;i&gt;The third component is from the Fund&#x2019;s fees and &lt;/i&gt; &lt;i&gt;expenses incurred during the Period.&lt;/i&gt;&lt;/div&gt;

The second component is the aggregate impact on the Fund&#x2019;s performance due to changes in other variables that impact FLEX Options prices - these include changes in a) the Reference Asset&#x2019;s dividends, b) interest rates, c) implied volatility, and d) time to option expiration. &lt;/i&gt; &lt;i&gt;The third component is from the Fund&#x2019;s fees and &lt;/i&gt; &lt;i&gt;expenses incurred during the Period.&lt;/i&gt; &lt;/div&gt;</oef:FactorsAffectingPerfTextBlock>

The second component is the aggregate impact on the Fund&#x2019;s performance due to changes in other variables that impact FLEX Options prices - these include changes in a) the Reference Asset&#x2019;s dividends, b) interest rates, c) implied volatility, and d) time to option expiration. &lt;/i&gt; &lt;i&gt;The third component is from the Fund&#x2019;s fees and &lt;/i&gt; &lt;i&gt;expenses incurred during the Period.&lt;/i&gt;&lt;/div&gt;

We attribute (allocate) the impact on the Fund&#x2019;s performance into three components. The first of the three components is the impact on the Fund&#x2019;s performance due to changes in the &lt;/i&gt; &lt;i&gt;Fund&#x2019;s&lt;/i&gt; &lt;i&gt; Reference Asset. The second component is the aggregate impact on the Fund&#x2019;s performance due to changes in other variables that impact FLEX Options prices - these include changes in a) the Reference Asset&#x2019;s dividends, b) interest rates, c) implied volatility, and d) time to option expiration. &lt;/i&gt; &lt;i&gt;The third component is from the Fund&#x2019;s fees and &lt;/i&gt; &lt;i&gt;expenses incurred during the Period.&lt;/i&gt; &lt;/div&gt;</oef:FactorsAffectingPerfTextBlock>

The second component is the aggregate impact on the Fund&#x2019;s performance due to changes in other variables that impact FLEX Options prices - these include changes in a) the Reference Asset&#x2019;s dividends, b) interest rates, c) implied volatility, and d) time to option expiration. &lt;/i&gt; &lt;i&gt;The third component is from the Fund&#x2019;s fees and &lt;/i&gt; &lt;i&gt;expenses incurred during the Period.&lt;/i&gt; &lt;/div&gt;</oef:FactorsAffectingPerfTextBlock>

The second component is the aggregate impact on the Fund&#x2019;s performance due to changes in other variables that impact FLEX Options prices - these include changes in a) the Reference Asset&#x2019;s dividends, b) interest rates, c) implied volatility, and d) time to option expiration. &lt;/i&gt; &lt;i&gt;The third component is from the Fund&#x2019;s fees and &lt;/i&gt; &lt;i&gt;expenses incurred during the Period.&lt;/i&gt; &lt;/div&gt;</oef:FactorsAffectingPerfTextBlock>
